Given
ln(ab) = b⋅ln(a)
Then
ln(1x) = x⋅ln(1)
Also
ln(2x) = x⋅ln(2)
Say
ln(2x) = ln(1x)
Then Also
x⋅ln(2) = x⋅ln(1)
But, dividing both sides by x
ln(2) ≠ ln(1)
Similarly,
x⋅ln(2) = x⋅ln(1)
Dividing both sides by x and ln(2)
1 ≠ 0
But we know x = 0 as per the original statement.
The question then is which algebraic step(s) was(were) wrong, and why?
